Title:

POLYESTER-BASED RESIN PARTICLES, PROCESS FOR PRODUCING SAME, AND USE THEREOF

Document Type and Number:

WIPO Patent Application WO/2017/056773

Kind Code:

A1

Abstract:

Polyester-based resin particles which comprise a polyester-based resin as a base resin, wherein the base resin, in analysis by DSC, has a plurality of endothermic peaks corresponding to crystal fusion temperatures, the endothermic peaks including at least one peak present in a lower-temperature-side region and at least one peak present in a higher-temperature-side region, and the maximum endothermic peak in the lower-temperature-side region and the maximum endothermic peak in the higher-temperature-side region showing a ratio of heat of crystal fusion therebetween, (heat of lower-temperature-side crystal fusion)/(heat of higher-temperature-side crystal fusion), in the range of 0.1-1.5. The polyester-based resin particles have a volume-average particle diameter of 1-50 µm.
